Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given a mutation tool with no annotations, 50% schema coverage, and no output schema, the description is incomplete. It lacks details on behavioral aspects (e.g., permissions, effects), parameter context (e.g., 'id' format), and expected outcomes. More information is needed for safe and effective use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
